To (Ml wit/m2, 11/ pm cmtccrn:

lle it known that we, l ion/up i5. tin/nu no and lmunmns l. l l iinn, citizens of the llnited l ltates. resiilin;- at liithopolis, in the county ol' lli airlield and tltate oi tlhio, have invented certz'iin new and use l ul improvements in M ilkingdllach i nesmt which the Following is a specilication.

This invention deals with the type of machines lior extracting the lacteal lluid l'rom the udder of a cow Ivy Vitfllll'llll-Pl\SFHHO and is designed to provide a cmitrivance of simple and ell'ective construction and which will not irritate or vex the animal during" the milking operation or prod nce serious results.

For a full description ol the llltoiltlml and the merits thereof and also to acqn ire a knowledge of the details cl. construction ol the means for ellj'ecting the result reference is to he had to the following description and acconl 'ianying drawings.

l'l hile the essential and characteristic features of the invention are susceptihleol modification. still the preferred embodiment of the invention is illustrated in the accompanying drawings, in which Figure l is a perspective view of a milkingmachine embodying the invention, showing it in active operation. liig'. 2 is a detail section of the machine. Fig. 3 is a perspective View of the iteat-ciu'is and their support on a larger scale. liig. 4t is a detail section ol the triiat-cnp support.

ilorrcs 'ionding and like parts are rel erred to in the lolliuvirne' description and iruliimted in all. the views of the drawings h v the same reference chmacters.

llhe support in general appearance resemhles a stool or stand and comprises a head it and legs 2. ilpon this support or stand is mounted a vaclnnn--creating device or airpninp, which in its simplest form, as shown, consists oi a cylinder (3 and piston T. l t. le-- ver ti, lnlcrmned to a stz'tndard 9 ol' the cylinder 6, is coni'iected with the stem of the piston 7 for operating the latter when desired. It stai'ulard l0, projected upward from the cyl inder c. is 'lorkcd at its upper end, as shown at l 2., to receive the pipe and support carryins the teat-cups. liipcs l3 and i l. connect with the lower portion ol the cylinder 6, an inwardl v-opening valve to co '5peratin;. with the pipe 12) and an n1iwardly-opening valve [6 COlllltfl'itldllil' with the pipe l-el. The element .13 is the inductimp-pipe and the element 14. the eduction--pipe and is adapted to deliver the milk into the pail 17.

A plate or support is attached to the outer end 01 the induction-pipe i3. A, compart ment 3 is provided in the plate and is closed at its upper side hy means of a transparent plate 4-, prc'lerahly of glass, so as to admit of ohserving the passage ol the milk through the compartment 3 during operation ol. the machine. The plate A; is removahly litted to admit of access to the interior ol the compartment 3 for cleaning or other purposes. The pipe 13 connects with the plate so as to comn'iuniczuie with one end of the coi'npartment 3. A series ol ducts l7 radiate from the opposite end portion ol the ccnnpartment 3 and may be tubes or other term of passages. The teat-cups 18 are cormectcd at their lower ends with the outer ends of the ducts or passages 1'7 by means ol flexible connections 19, which will admitoi relative movement oi? the teat-cups at their free ends, so as to adapt themselves to the position ol the teats upon dil'ferent cows.

The teat-cups 18 are arranged in a cluster and are of tapering Form and time at their upper ends, as indicz'ited at 20, so as to come in contact with the udder and prevent undue n'essu re thereon while at the same time maintaining lirm connection, which is essential to the ell'cctivel'iess oi the apparatus. The cups iii are M such relative size as to comfortably receive the tens without producing; lateral pressure thereon to obstruct the free flow of the lacteal fluid, and the llared ends hear against the udder, preventing drawing of the same into the cups when the piston T is moved to create a racuunrpressure within the cylin der and cups.

[is iiulicated in llig. 1, the ainpump is sup iiorted upon the stand, and the lower end of the educting-pipe let is arranged to discharge in to the pail or receptacle 117 when the cups 18 are litted to the teats and closed against the udder. Upon moving the piston 7 upward in the cylinder 6 the valve 16 closes and the valve 15 opens, thereby permitting the creation of a vacuum within the teat-cups 18 and cansing a suction upon the teats, which causes the milk to flow from the udder into the cups 18, thence through pipe 13 into the cylinder 6. A downward pressure upon the piston 7 closes valve 15 and opens valve 16 and discharges the milk from the cylinder 6 into the pail 17. An upward stroke of the piston 7 again creates a vacuum-pressure and usually results in completely extracting the milk from the udder, the parts being of such relative size as to necessitate but two strokes of the piston to effect the milking of each cow. The stoppage of the flow of the milk at the end of the operation may be observed through the transparent plate 4., as will be readily comprehended. \Vhennot in position, the teat-cups, their support, and the pipe 13 are held out of the way by placing the pipe 13 in the fork 12 of the standard 10.

Having thus described the invention, what is claimed as new is 1. In a milkingmachine, a head provided with a compartment, a transparent plate closing a side of said compartment to admit of both access thereto and observation of the milk in its passage therethrough, and milk extracting and discharging means connected with said compartment to cause circulation of the milk therethrough, substantially as described.

2. In a milkingmachine, the combination of a support provided with a compartment having a portion closed by means of a transparent plate, ducts radiating from an end portion of said compartment, teat-cups connected with the outer ends of said ducts and an induction-pipe connected with the opposite end portion of said compartment, substantially as set forth.

3. A milking-machine comprising a stand, a vacuum-creating device mounted upon said stand and having an inlet and an outlet, pipes communicating with said inlet and outlet, inwardly and upwardly opening valves controlling respcctively the said inlet and outlet, a head provided with a compartment having a portion closed by means o l a transparent plate, ducts radiating from said compartment and teat-cups For connection with the outer ends of said d ucts, substantially as set forth.

In testimony whereof we aiiix our signatures in presence of two witnesses.
